PIVO'IED WINDOW.

Specification of Letters'lPatent. Patented N V. 3, 1914.

Application filed November 1, 1913. Serial No. 798,722.

To all whom it may concern:

'Be it known that I, STEPHEN VIRAGH, a resident of Swissvale, in the county of AL legheny and State of Pennsylvania, have 1nvented a new and useful Improvement in Pivoted Windows, of which the following is a specification.

This invention relates to sliding and swinging sash windows, and particularly to windows embodying a sash rotatably connected to runner members which slide in grooves or runways in the pulley stiles.

The object of the invention 1s to prov de a sliding and swinging sash window, having interlocking parts on the sash and runners extending from top to bottom thereof and thereby entirely preventing the entrance of air or moisture through the sash, wherein the hinge parts are almost entirely concealed between the sash and runners, but are nevertheless arranged so as not to interfere with the air tightening or interlocking members, and wherein the sliding runner and sash stile are locked together by the interlocking parts provided thereon and by the hinge leaves so that warping or loosening of the parts is prevented.

The invention comprises the construction and arrangement of parts hereinafter described and claimed. I In the drawings Figure 1 represents front elevation of the lower portion, of a window and frame embodying the inven tion; Fig. 2 is a side elevation of the sash, as the same appears viewed from the left, Fig. 1, and showing the sash in full lines at the beginning of its reversing movement, and in dotted lines near the end of said movement; Fig. 3 is a cross section on the line 33, Fig. 1, on an enlarged scale, looking in the direction of the arrows; Fig. 4: is a cross section on the line 14, Fig. 1, looking in the direction of the arrows; Fig. 5 is a detail side elevation, on an enlarged scale, of a special form of hinge; Fig. 6 is a plan or edge View of the hinge; and Fig. .7 is a perspective View of one of the runners.

The sash shown in the drawings comprises a top rail 1, bottom rail 2, and two vertical side members, each of which comprises a stile 6, and an extra member or runner 7, which travels along the runways 3 of the pulley stiles 1, which may be of any suitable construction. The stile and runner are provided with interlocking portions to secure a close fit therebetween and prevent the entrance of air or moisture from the outside of the window. In the form shown in the drawings, the runners 7 areprovided with longitudinal ribs 8, and the stiles with ribs 9, disposed oppositely to ribs 8. Ribs 8 and 9 extend vertically for the full length of the runner and stile, and are undercut or otherwise formed on anlincline, asat 13. They may be either integral with, or secured to the stile 6 and runner 7 as desired. To interlock or match with the ribs 8 or 9, the stile 6 and runner 7 are respectively provided with ribs 10 and 10, as shown in Figs. 3, land 7. Rib 10 is suitably secured to the'upper half of stile6 and is exactlyohalf the length thereof. Rib 10 is of the same shape in Fcross section as rib 1O? and is of the same length, that is, half the height of the sash, and is secured to the lower half of the runner. The two ribs 10 and 10 also abut end to end exactly midway of the height of the sash. I

Stile 6 and runner are hinged together, the hinges each comprising two leaves 11, consisting of fiat metal plates and lying in planes parallel to each other and slightly offset from each other. Said leaves have end edges 13 and bottom edges 13, the latter being partly straight and partly curved, as

-- at 13, on the arc of a circle, and extending up to the front face of edge 12 of the leaf.

receive a nut 18. Both of "the leaves 11 are provided with one or more suitably spaced apertures 19 for securing them to the window parts, as hereinafter described.

Rib 10 on the stile 6 is cut away or mortised'on its face next to the stile to form a socket 20. This socket may be formed by a rotating cutter, and consequently by a machine operation. It is preferably shaped with a partly straight and partly circular bottom corresponding to the shape of the hinge leaves 11. Rib 10 is likewise provided .with a socket 21, having a partly straight and partly circular bottom and mortised out of said rib on that side next to the runner.

Sockets 20 and 21 are provided to receive the two hinge leaves 11, and the latter are secured, one to the stile 6, and the other to the runner 7, by screws 22 passing through lines Fig. 2, the two hinge leaves 11 he wholly on opposite sides of the pivot,that hinge leaf which is secured to the stile 6 being above the pivot, and that which is secured to runner 7 being below the pivot. The end edges 18* of the leaves lie in a common plane normal to the length of the stile and runner through the hinge axis. When the window is rotated to open position, as shown in dotted lines Fig. 2, no parts of the hinge leaves project from the ribs 10 or 10-. Moreover, the hinge leaves are buried in said ribs and are therefore concealed, the only exposed parts being the pivot lugs and the edges of the leaves. The construction is therefore pleasing to the eye and also is more durable as the hinge parts are protected from corrosion and rust. Again, each hinge leaf is arranged to fit its socket snugly so that it is more securely and immovably attached than if merely screwed to the face of the stile or runner. Further, the construction does not break the continuity of the interlocking parts which eX- tend unbroken the whole length of the sash, nor does it interfere with the abutment of the ribs 10, 10 at the middle of the sash. In the whole length of the interlocking joint between sash stile and runner there is no portion mortised or cut away for the hinges or any other parts, to form points of leakage for air and dust to enter as in prior pivoted sash windows.

What I claim is:

1. In a sliding and swinging sash window, a sash having side members each comprising a stile and a runner, said stile and runner being each provided with a mortise, said mortises being offset from each other transversely to the length of the stile, the stile andrunner each having a portion overlying the side of its respective mortise, and a hinge having two leaves offset from each other and secured in said mortises.

2. In a sliding and swinging sash window, a sash having side members each com prising a stile and a runner, said stile and runner being each provided with a mortise, saidmortises opening outwardly only from the face of the sash and being offset from each other both longitudinally and transversely to the length of the stile, the stile and runner each having a portion overlying the side of its respective mortise, and a hinge having two leaves oifset from each other longitudinally of the hinge pintle and extending in opposite directions from said pintle and secured in said mortises.

In testimony whereof, I have hereunto set my hand.
